ngrok

ngrok is a developer platform that provides secure ingress, routing, and connectivity for applications, APIs, and AI models through a single programmable gateway. Founded by Alan Shreve and headquartered in San Francisco, the platform serves enterprise customers including Databricks, OpenAI, Microsoft, Twilio, Zoom, Grafana, Okta, Vercel, GitHub, Hugging Face, Perplexity, and Ramp. The product originated as a simple localhost tunneling tool for exposing development servers to the public internet but has expanded into a universal gateway that handles API routing, webhook delivery, load balancing, authentication, and traffic inspection. The AI Gateway feature allows teams to route requests across multiple language model providers with automatic failover, rate limiting, and observability, simply by changing a single base URL in their application code. The platform supports Model Context Protocol server connectivity, enabling AI coding agents like Claude Code and Cursor to access remote MCP servers through authenticated tunnels. ngrok provides native integration with Kubernetes for projecting local development environments into remote clusters, and supports Docker, Terraform, and CI/CD pipeline deployment patterns. Enterprise security features include SOC 2 Type II certification, HIPAA compliance with Business Associate Agreements, GDPR and CCPA compliance, EU-US Data Privacy Framework certification, role-based access control, SAML SSO with SCIM provisioning, comprehensive audit logs, data residency controls, and white-labeling for custom domains. The gateway handles TLS termination, custom certificate management, HTTP header manipulation, and IP allowlisting. Developer advocates including Kent C. Dodds, Yehuda Katz, and Cassidy Williams publicly endorse the platform for its reliability in webhook testing and preview environment workflows.
